How to choose the right cordless screwdriver.

Practically the majority of construction tools users prefer to have the farm-purpose tool.Motifs such aspirations are quite natural: to have more rational in the economy is one tool that is able to replace several.Save money and space in the closet shelves obvious.However, all things exist as its own advantages and disadvantages, and versatile tool with battery does not constitute an exception to this general rule.Site apartment repair on its own tells how to choose a screwdriver properly and that it is better to pay attention.Share your opinion and leave some feedback.

Therefore, the user sh

ould keep in mind that choosing a universal tool, he deliberately allows the averaging of some characteristics, according to which the quality of the instrument is estimated, for example drilling rate or impact force.Moreover, some characteristics of the instrument are simply incompatible, such as hammer drilling and drilling small diameter holes.Instead, the user enjoys all the benefits inherent versatility such as:

  • tool with battery provides a battery life of household electric
  • multifunctional tool provides ample opportunities of its application
  • simplicity and accuracy

And this is a partial list of the universal instruments features.Currently, manufacturers of a wide range of different models of rechargeable universal tools such as: screwdrivers, sanders, planers, and more.This tendency displace conventional network tools cordless tools, not only in use but also in the production and in industry.In the article, given the urgency of the issue, the correct choice of instrument, examines in detail the features of the cordless screwdrivers.Our choice is the online store price available all the tools that work in many cities and showed the authority to work.

cordless universal tool - the advantages and disadvantages

It is obvious that the optimum tool selection is primarily determined by the tasks, the solution of which the tool should provide and, of course, the conditions of its future operation (operation in a domestic environment or the decision of professionaltasks).A clear understanding of the future operating conditions is even more important when you consider that the cost of multi-functional household tools is not much different from the cost of the professional cordless screwdrivers.Logically the question arises - what distinguishes a professional tool of domestic models.The main difference is manifested in the fact that a professional screwdriver can withstand longer load and less careful handling.

These settings and features professional models from simple, so many manufacturers in the data sheets indicate that their product does not lose its efficiency after a fall from a certain height.It should also be noted that even in the repair tool designed for domestic use, operated less intensively than in a production environment.However, such high resource strength and reliability provided by the functionality.For this reason, a professional tool is less functional than the household.

For a clearer understanding of the subject matter, it is necessary to analyze the situation by considering a specific example.Suppose that in some furniture shop received a batch of universal cordless screwdrivers QUATTRO brands, each of which represents a 4 screwdrivers in one of the brand Black & amp; Decker KC2002FK.

On the surface, it seems that the production of furniture equipped with excellent technique, produced by well-known brand, and thus saved quite a decent amount of money (the cost of a set of 6000 p., Whereas the standalone tool does not cost much cheaper).But this judgment is rather superficial.Let us consider the question thoroughly.In production practically always of time necessary to perform the same operation or planing wood, or to engage in the installation of the finished product, or solve problems of packaging products.It is not difficult to guess that only requires one tool (eg, jig saw, planer, screwdriver, etc.) to perform the same type of functions.All will become clear if we compare the characteristics of the screwdriver with nozzles Black & amp; Decker KC2002FK and characteristics of the individual instrument.Choose this versatile cordless screwdriver those who do not so often used the individual components, and indeed this tool.

For greater clarity, it makes sense to consider all products of the same brand Black & amp; Decker at a bargain price, namely screwdriver Black & amp; Decker CR12K, the value of which is 3.5 thousand rubles..In screwdrivers KC2002FK type is used battery capacity of 1.5 ampere / hour and a voltage of 14.4 V, while in no universal model used battery capacity of 1.5 ampere / hour and 12 V, but the value of its torque is 16 Nm, while the more powerful universalscrewdriver just 10.5 Nm.The first significant sacrifice to ensure the universality of the device.

versatile tool can be used as a jigsaw to which, of course, impose special requirements does not make sense.Jigsaw same firm KS999EK has 600 watts, and the adjustable frequency canvas strokes varies from 0 to 3200 strokes / min.

nozzle universal device demonstrates the same stroke frequency (3000 strokes / min), but it can help to cut the material to a depth of 38 mm and a specialized fret tree is cut up to 65 mm.

Who better to choose this instance?Universal screwdriver with nozzles Black & amp; Decker KC2002FK is an ideal tool for use in the home in which it is used only when necessary, that is quite rare.Its use in the production of meaningless, and therefore in a professional environment are widely used specialized tools, equipped with the same type of the battery pack and perform well-defined, standard features.
